The Pan Bottom Linear Abrasion Testing Machine (also referred to as a Linear Abraser or Coating Scrub Tester) is a specialized instrument designed to evaluate the wear resistance and durability of non-stick coatings on cookware surfaces. This equipment simulates repeated mechanical abrasion that occurs during everyday use—such as scrubbing, utensil contact, and general wear—to provide quantitative data on coating longevity and performance.

Designed to meet stringent safety standards including UL 60950 (Information Technology Equipment Safety) and UL 62368 (Audio/Video, Information and Communication Technology Equipment Safety), this tester is essential for manufacturers seeking to validate product reliability and compliance with international quality requirements.

• Non-stick cookware coating wear resistance testing
• Frying pans, saucepans, and wok bottom durability evaluation
• Coating scrub resistance for household metal cooking utensils
• Quality control and R&D for cookware manufacturers

The Linear Abrasion Testing Machine operates on a reciprocating linear motion principle, simulating the back-and-forth scrubbing action of cleaning tools or cooking utensils against the pan bottom surface.

The testing system incorporates a horizontal arm that reciprocates in a linear motion across the test specimen surface. Attached to the end of the arm is a precision bearing spline shaft that creates a "free-floating" test system, permitting vertical movement as the test attachment follows the contours of the pan bottom. Weight discs are mounted on top of the shaft to apply controlled pressure.

As the horizontal arm strokes back and forth, the test attachment moves across the coated surface, generating consistent, repeatable wear patterns. This design ensures uniform abrasion across the test area, producing accurate and reliable results.

• Frame: Heavy-duty powder-coated steel for stability
• Drive System: Precision motor with reciprocating mechanism
• Test Attachments: Interchangeable heads for various abrasion media
• Specimen Holder: Adjustable clamping system for pans of different sizes
• Control Panel: User-friendly interface with preset programs

The tester accommodates various abradant types to simulate different wear conditions:

• Steel Wool Pads (#0000 grade) - Simulates aggressive scrubbing
• CS-10F Wearasers - Standardized abrasive erasers
• MIL-12397 Erasers - For specific aerospace applications
• Custom Abradants - Tailored to specific coating types
